AddDataSeries(Data.BarsPeriodType.Tick, 1) vs Calculate = Calculate.OnEachTick

[billythekid72]

Hello,

In my strategy, I have two data series, one is set up with Calculate = Calculate.OnBarClose; and the other set up with AddDataSeries(Data.BarsPeriodType.Tick, 1) .
With that setup, my OnBarUpdate() will be called on every tick as well on every bar closed. Is my understanding correct? Thanks

Hello Billy,

Thanks for your post.

Calculate.OnBarClose is not a data series. The Calculate method determines how often OnBarUpdate() is called. If this is set to OnBarClose, the OnBarUpdate() method will process at the close of each bar.

See this help guide page about Calculate: https://ninjatrader.com/support/help.../calculate.htm

AddDataSeries() will add a secondary data series to your script. That added series can be used to calculate values or place trades based on that series.

See this help guide about AddDataSeries(): https://ninjatrader.com/support/help...dataseries.htm

For example, Close[0] could be used to get the close price of the primary series the script is running on. Closes[1][0] could be used to get the close price of the first added data series.

Hello Brandon,

Thank you for your reply. It is my understanding that with AddDataSeries(Data.BarsPeriodType.Tick, 1), the OnBarUpdate() will be called on every tick, in addition to the on Bar closed. Is that correct? Thanks.

Hello Billy,

Thanks for your note.

Yes, AddDataSeries() will add the secondary Tick series to the script which will calculate at the close of each bar.
